other insurance clause
An other insurance clause is a provision found in both property and liability insurance policies establishing how loss is to be apportioned among insurers when more than one policy covers the same loss.
Additional Information
These provisions vary: some policies provide no coverage when other insurance is in place, some pay a pro rata share, and others apply in excess. They are included to comply with the principle of indemnity, which states that an insured should not profit from an insured loss.
